В моем прилагаемом приложении Electron я извлекаю проект узла в определенное место. Есть сценарий, который должен запускать npm install, и когда я запускаю его через spawn, я получаю сообщение об ошибке: npm не найден.
Код, который я использую:
const process = spawn('my_script.sh', {shell: 'bin/bash', detached: true});
#!/bin/bash
cd <location of package.json>
npm install
В процессе отладки я сделал следующее:
- Команда может быть запущена, когда я открываю новую командную строку и запускаю
which npm указывает на /usr/bin.
Я проверил переменную PATH из сценария, запускаемого spawn (поместив
echo $PATH), и он вернул:
/snap/<app_name>/x1/usr/sbin:
/snap/<app_name>/x1/usr/bin:
/snap/<app_name>/x1/sbin:
/snap/<app_name>/x1/bin:
/usr/local/sbin:
/usr/local/bin:
/usr/sbin:
/usr/bin:
/sbin:
/bin:
/usr/games:
/usr/local/games:
/snap/<app_name>/x1/gnome-platform/usr/bin
, который включает / usr / bin
Затем я распечатал содержимое / usr / bin из сценария (добавлен
ls -l /usr/bin) и заметил, что npm, node и yarn не были в нем. Затем я открыл новое окно и запустил команду напрямую, и список был значительно длиннее, чем то, что было возвращено сценарием.
Результат ls -l /usr/bin при запуске из сценария (отсутствующий узел, пряжа, npm и бесчисленное множество других файлов):

Так что по какой-то причине содержимое / usr / bin отличается при доступе из командной строки моего дистрибутива против созданного скрипта (1745 против 317 строк, напечатанных при добавлении | wc -l).
